Beer cooling and dispensing system



Dec. 29, 1936. H. .1. SANDELL BEER COOLING AND DISPENSING SYSTEM Filed Oct. 6, 1955 Patented Dec. 29, 1936 UNITED STATES PATENT OFFICE 5 Claims.

The invention relates to a beer cooling and dispensing system, and has for its object to simplify and improve the efficiency of drawing beer from a storage refrigerator at one point and a dispensing 5 outlet at another.

The chief object of the invention is to provide a combination of devices adapted to contain an enclosed circulating and cooling medium, for the purpose of maintaining a uniform low tempera- 10 ture along a dispensing pipe contained therein.

Explanation In beer cooling and dispensing, the beer storage refrigerator is usually placed in the basement or some other convenient place that requires consid- 15 erable piping and a coil to carry the beer and cool it from the storage refrigerator to the counter dispensing coil box. When this system is used, the beer leaves the cold refrigerator and runs exposed, then enters the iced coil, but due to the difierent go and uneven temperatures along the line of draught the beer cannot be drawn or controlled at the faucet without considerable waste.

It is of course understood that beer is a very sensitive product to an uneven temperature,

25 either of a warm or cold nature.

My invention provides an extremely simple and eflicient means whereby the coil is eliminated, the temperature can always be kept even all along the line of draught, the beer can be drawn with- 30 out waste and with its natural flavor. The degree of temperature in the system can be regulated by the speed of the motor, which is either controlled manually by a switch on the counter or a thermostatjnstalled in the upper part of the stack.

85 Referring to the drawing:

Fig. 1 is a vertical section with some parts shown in full and with some parts broken away illustrating my invention.

Fig. 2 is a cross section of the temperature ex- 40 changer, the fan or blower, cooling and outlet chambers and the motor.

Referring first to the illustration of Fig. 1, the numeral I indicates a portion of an ordinary beer storage box or refrigerator equipped with 45 refrigerating coils 2. The numeral 3 indicates a portion of a counter or bar. Numeral 4 indicates a counter dispensing cooler box, provided with a drip pan 5, which is equipped with a drain pipe to take care of any waste that may occur. Nu-

60 meral I is a bar drainer. Numeral 8 indicates a dispensing tube or pipe which runs from the beer barrel located in the refrigerator, up through an insulated conductor pipe or stack l0, to dispensing faucet II. The means of providing pressure 55 to force the beer from barrel 9 to faucet ll through pipe 8 might be either air from an air compressor or gas from a drum. Stack I is provided with suitable gaskets or closure means l2, where the dispensing pipe 8 enters and leaves stack I0 to prevent leakage of enclosed circulating and cooling medium. Insulated stack I0 is the cooler connector between the temperature exchanger I3 and dispensing faucet H, stack l0 contains two passage ways or ducts A and AB. Passage A is the cooling medium outlet which 10 contains dispensing pipe 8. AB is the return passage, the two passages being connected near the uls ensing outlet. Numeral I4 indicates an insulated casing of stack l0. Numeral l3 indicates a temperature exchanger or closed casing having a cooling chamber AA internally arranged with fins or lugs B, the latter are the means I provide to exchange or transfer a low temperature from the refrigerating coils 2 to the enclosed circulating and cooling medium, an outlet chamber A containing a fan or blower l5 which is the means for forcing a continuous circulation of the cooling medium, numeral l5 may be driven by any means available, I have shown it driven by a small electric motor attached thereto, both chambers having their respective inlet AB and outlet A passages to connect to like passages in stack [0 so as to afford a continuous passage for the circulation of the enclosed cooling medium from the temperature exchanger l3 through the stack I 0 and back to the temperature exchanger. As is evident, when the enclosed fan or blower I5 is rotated by motor IS the enclosed cooling medium will be forced through the stack l0 and constantly maintaining a low uniform temperature along dispensing pipe 8. Numeral I1 is an opening I provide as an outlet means for stack l0 and temperature exchanger l3. Numeral I6 is a small motor which drives the fan or blower. The motor can be either controlled manually by a switch on the counter, or automatically controlled by a thermostat switch 20 which is controlled by thermal bulb l9 installed in or at the upper part of the stack Ill, thus providing the means of controlling the degree of temperature of the cooling and circulating medium. Numeral 2| is a closure means around the combined motor and blower shaft. The cover plate i8 is purposely left off in Fig. 1 to show the fan or blower.

It will be understood that the device as described herein as the preferred form is capable of modifications within the scope of the invention disclosed and claimed.
